摘要
线性调频信号等抗干扰波形的设计和使用,使雷达在各种复杂杂波和人为噪声干扰的情况下,仍然具有良好的检测跟踪能力。针对这个问题,在现有的脉冲、噪声卷积干扰的基础上提出了基于三角波调制的卷积干扰技术以提升干扰性能:给出了通用的时域卷积调制干扰的数学模型,在此基础上分析了三角波卷积干扰的信号形式,对其干扰效果进行了仿真实验并说明其优势所在。结果表明,通过控制三角波的参数可以达到欺骗和遮盖的不同效果且具有独特优势。
The design and application of anti-jamming waveforms such as LFM signal,make the radars still have the good ability to detect and track under the circumstances about complex clutter and noises.In order to solve this problem and gain better jamming effect,the convolution jamming technique based on the triangle wave modulation is built up under the pulse and noise convolution jamming,and the generic convolution jamming model in the time domain is designed,then its characteristics and jamming effects are analyzed,and the advantages are explained by simulation at last.The results show that triangle wave convolution modulation can realize the double jamming effects of deception and masking under the change of parameters,and also has the unique advantage.
